Check Digit Verification of cas no

The CAS Registry Mumber 69688-96-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,6,8 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 69688-96:
(7*6)+(6*9)+(5*6)+(4*8)+(3*8)+(2*9)+(1*6)=206
206 % 10 = 6
So 69688-96-6 is a valid CAS Registry Number.

Benzothiazole Sulfinate: A Sulfinic Acid Transfer Reagent under Oxidation-Free Conditions

Day, Jacob J.,Neill, Deshka L.,Xu, Shi,Xian, Ming

supporting information, p. 3819 - 3822 (2017/07/26)

Sulfinic acids are commonly encountered intermediates found in natural product synthesis and medicinal chemistry. However, because of high reactivity, instability, and harsh reaction conditions, they are difficult to synthesize. Herein we have developed an oxidation-free method to produce sulfinic acids and sulfinate salts using 2-sulfinyl benzothiazole (BTS). We have also demonstrated the synthetic usefulness by developing one-pot syntheses of sulfones and sulfonamides.
