Check Digit Verification of cas no

The CAS Registry Mumber 1316859-74-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,6,8,5 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1316859-74:
(9*1)+(8*3)+(7*1)+(6*6)+(5*8)+(4*5)+(3*9)+(2*7)+(1*4)=181
181 % 10 = 1
So 1316859-74-1 is a valid CAS Registry Number.

Synthesis of diarylmethanes via metal-free reductive cross-coupling of diarylborinic acids with tosyl hydrazones

Li, Xijing,Feng, Yuanyuan,Lin, Lin,Zou, Gang

, p. 10991 - 10995 (2013/02/22)

This paper describes a practical and efficient procedure that takes advantage of diarylborinic acids as a cost-effective alternative to arylboronic acids for synthesis of diarylmethanes through metal-free reductive cross-coupling with N-tosylhydrazones of aromatic aldehydes and ketones. The procedure tolerates hydroxyl, halide, amine, and allyl functionality, complementary to the transition-metal catalyzed cross-coupling techniques.
