Check Digit Verification of cas no

The CAS Registry Mumber 2225-27-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,2 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2225-27:
(6*2)+(5*2)+(4*2)+(3*5)+(2*2)+(1*7)=56
56 % 10 = 6
So 2225-27-6 is a valid CAS Registry Number.

New and facile synthesis of thiosulfonates from sulfinate/disulfide/I2 system

Fujiki, Kiyoko,Tanifuji, Naoki,Sasaki, Yohei,Yokoyama, Taku

, p. 343 - 348 (2007/10/03)

Thiosulfonates were prepared by the iodine oxidative sulfenylation of sulfinates with various disulfides in good yields both in the presence and absence of solvent. One of the important biological applications of sulfenylation is the reaction of cyclic disulfides.
