Check Digit Verification of cas no

The CAS Registry Mumber 1401229-74-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,1,2,2 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1401229-74:
(9*1)+(8*4)+(7*0)+(6*1)+(5*2)+(4*2)+(3*9)+(2*7)+(1*4)=110
110 % 10 = 0
So 1401229-74-0 is a valid CAS Registry Number.

First total synthesis of epicoccarine A via O- to C-acyl rearrangement strategy

Ujihara, Yasuaki,Nakayama, Ken,Sengoku, Tetsuya,Takahashi, Masaki,Yoda, Hidemi

, p. 5142 - 5145,4 (2012/12/12)

The first total synthesis of antibacterial epicoccarine A isolated from a fungus Epicoccum sp. has been accomplished in 10 steps along with synthetic elaboration of its C5-epimer, highlighting the utility of O- to C-acyl rearrangement of a 4-O-acyltetramic acid derivative. Comparison of spectroscopic properties and specific optical rotations of the synthetic samples with those reported for authentic material has clearly indicated the unspecified absolute stereochemistry of this natural product to be 5S.
