Check Digit Verification of cas no

The CAS Registry Mumber 77333-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,3 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77333-20:
(7*7)+(6*7)+(5*3)+(4*3)+(3*3)+(2*2)+(1*0)=131
131 % 10 = 1
So 77333-20-1 is a valid CAS Registry Number.

Metall-Bor-Verbindungen, 13. Zur Synthese und Reaktivitaet einiger (Trimethylstannyl)borane

Noeth, Heinrich,Schwerthoeffer, Ruediger

, p. 3056 - 3062 (2007/10/02)

The preparation of some amino(trimethylstannyl)boranes and their chemical properties are described.With Me3SnLi (Me = CH3) as a reagent only the synthesis of Me3SnB(NR2)2 (1a, b), Me3SnBCl(NR2) (2a, b), and (Me3Sn)2BNR2 (3b) was achieved.The stannylboranes Me3SnB(NR2)2 show astonishing thermal stability.Their Sn - B bonds are broken by hydrogen, the halogens, and chalcogens as well as by alcohols.HCl cleaves the B - N bond.
