Check Digit Verification of cas no
The CAS Registry Mumber 21849-27-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,4 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21849-27:
(7*2)+(6*1)+(5*8)+(4*4)+(3*9)+(2*2)+(1*7)=114
114 % 10 = 4
So 21849-27-4 is a valid CAS Registry Number.

α-Sulfinyl carbenoid: One-carbon homologation of ketones to α-sulfinyl ketones using chloromethyl phenyl sulfoxide
Satoh, Tsuyoshi,Hayashi, Yasumasa,Mizu, Yasuhiro,Yamakawa, Koji
, p. 7181 - 7184 (2007/10/02)
Addition of the carbanion of chloromethyl phenyl sulfoxide to ketones gave the adducts, which were treated with lithium diisopropylamide to afford one-carbon homologated α-sulfinyl ketones via α-sulfinyl carbenoids in moderate to high yields.
