Check Digit Verification of cas no

The CAS Registry Mumber 3969-85-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,6 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3969-85:
(6*3)+(5*9)+(4*6)+(3*9)+(2*8)+(1*5)=135
135 % 10 = 5
So 3969-85-5 is a valid CAS Registry Number.

Surgical Cleavage of Unstrained C(sp3)?C(sp3) Bonds in General Alcohols for Heteroaryl C?H Alkylation and Acylation

Wang, Yaxin,Yang, Le,Liu, Shuai,Huang, Lixia,Liu, Zhong-Quan

, p. 4568 - 4574 (2019)

We reported herein a predictable and surgical cleavage of carbon-carbon bond in alcohols. A wide range of 1°, 2° and 3° alcohols including sugars and steroids without ring strain or steric hindrance were all compatible with this system. Also it offered a green and practical strategy for generation of alkyl/acyl radicals using alcohols as the sources. Besides, the features of visible-light-initiation, catalyst and metal free, excellent selectivity and mild conditions make it valuable and attractive. (Figure presented.).

THE ISOPROPYLIDENATION OF D-RIBOSE DIETHYL DITHIOACETAL AND RIBITOL. A NEW SYNTHESIS OF α- AND β-D-RIBOFURANOSYLETHYNE via 2,3:4,5-DI-O-ISOPROPYLIDENE-aldehydo-D-RIBOSE
