Check Digit Verification of cas no

The CAS Registry Mumber 136534-64-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,3 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 136534-64:
(8*1)+(7*3)+(6*6)+(5*5)+(4*3)+(3*4)+(2*6)+(1*4)=130
130 % 10 = 0
So 136534-64-0 is a valid CAS Registry Number.

Two-Step Protocol for Iodotrimethylsilane-Mediated Deoxy-Functionalization of Alcohols

supporting information, p. 1179 - 1183 (2021/02/01)

We have developed a two-step protocol for iodotrimethylsilane-mediated deoxy-functionalization of primary and secondary alcohols to afford products containing a C?N, C?S, or C?O bond. In the first step the alcohol undergoes iodination with iodotrimethylsilane, and in the second, the iodine atom is replaced by a N, S, or O nucleophile. Compared with traditional Mitsunobu reaction, non-acidic pre-nucleophiles can be used, and the reaction proceeds with retention of configuration. This operationally simple, highly efficient protocol can be used for some natural products and small-molecule drugs containing hydroxy-group.
