Check Digit Verification of cas no

The CAS Registry Mumber 75910-29-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,1 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75910-29:
(7*7)+(6*5)+(5*9)+(4*1)+(3*0)+(2*2)+(1*9)=141
141 % 10 = 1
So 75910-29-1 is a valid CAS Registry Number.

Silver(I)-Promoted Radical Sulfonylation of Allyl/Propargyl Alcohols: Efficient Synthesis of γ-Keto Sulfones

Fang, Guichun,Liu, Jianquan,Shang, Weidong,Liu, Qun,Bi, Xihe

supporting information, p. 3334 - 3338 (2016/12/14)

An efficient Ag2CO3-promoted sulfonylation of allyl/propargyl alcohols with sodium sulfinates has been developed. The reaction tolerates a wide range of functional groups to deliver γ-keto sulfones in high yields (up to 93 %). Propargyl alcohols furnished trimerization product 1,3,5-triaroylbenzenes in the presence of sodium methanesulfinate under the standard conditions. A mechanism involving a sulfonyl radical was suggested.
