Check Digit Verification of cas no

The CAS Registry Mumber 241153-85-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,1,1,5 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 241153-85:
(8*2)+(7*4)+(6*1)+(5*1)+(4*5)+(3*3)+(2*8)+(1*5)=105
105 % 10 = 5
So 241153-85-5 is a valid CAS Registry Number.

Synthesis of unit-B of cryptophycin-24 via Sharpless asymmetric dihydroxylation

Borah, Arun Jyoti,Goswami, Progyashree,Barua, Nabin C.,Phukan, Prodeep

, p. 7128 - 7130 (2012)

A synthetic pathway for the synthesis of unit-B of cryptophycin-24 has been developed using Sharpless asymmetric dihydroxylation as the key step. This study shows that direct azidation of α-hydroxy acid ester using diphenylphosphoryl azide is beneficial to asymmetric synthesis of α-amino acid without the loss of chirality during the transformation.
