121261-01-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121261-01-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,6 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121261-01:
(8*1)+(7*2)+(6*1)+(5*2)+(4*6)+(3*1)+(2*0)+(1*1)=66
66 % 10 = 6
So 121261-01-6 is a valid CAS Registry Number.

REACTION OF CHLOROSULFONYL ISOCYANATE WITH 1,2-DIOLS: REARRANGEMENT AND FORMATION OF CARBONATES
Joseph, Sajan P.,Dhar, D. N.
, p. 2295 - 2302 (2007/10/02)
1,2-Diols, 1a-e, upon reaction with chlorosulfonyl isocyanate (CSI) gave the ketones, 3a-e.Under similar experimental conditions, 1,2-diols, 1f-k, gave carbonyl compounds, 3f-k, carbonates, 6f-k, carboxamides, 7h,i, and the epoxide, 5i.
