Check Digit Verification of cas no

The CAS Registry Mumber 74260-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,6 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74260-31:
(7*7)+(6*4)+(5*2)+(4*6)+(3*0)+(2*3)+(1*1)=114
114 % 10 = 4
So 74260-31-4 is a valid CAS Registry Number.

Synthesis of Benzyltributylstannanes by the Reaction of N-Tosylhydrazones with Bu3SnH

Qiu, Di,Wang, Shuai,Meng, He,Tang, Shengbo,Zhang, Yan,Wang, Jianbo

, p. 624 - 632 (2017)

An efficient stannylation process with N-tosylhydrazones or directly with carbonyl compounds has been developed. A series of functionalized benzyl- and alkyltributylstannanes can be synthesized in moderate to good yields under transition-metal-free conditions. Tandem transformations involving stannylation/Stille cross-coupling reaction have been carried out without purification of the benzyltributylstannane intermediates to afford a series of diarylmethane derivatives.
