Check Digit Verification of cas no

The CAS Registry Mumber 1356941-22-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,6,9,4 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1356941-22:
(9*1)+(8*3)+(7*5)+(6*6)+(5*9)+(4*4)+(3*1)+(2*2)+(1*2)=174
174 % 10 = 4
So 1356941-22-4 is a valid CAS Registry Number.

Mechanistic variations in ionic hydrogenation of unsaturated phosphine and amine boranes

De Vries, Timothy S.,Majumder, Supriyo,Sandelin, Angela M.,Wang, Guoqiang,Vedejs, Edwin

, p. 688 - 691 (2012/04/17)

Internal hydride transfer occurs when tethered carbocations are generated from unsaturated phosphine or phosphinite boranes. 3-Methylenecyclohexyl-derived boranes 12 or 18 react with MsOH to give ionic hydrogenation products with high syn-selectivity. With unsaturated amine boranes, initial hydrogen evolution gives BH2(OMs) complexes, but IH occurs using excess MsOH in a slower second stage. A diastereoselective reaction occurs from 26b using camphorsulfonic acid (first stage) and MsOH (second stage), affording 33 (68% ee) after hydrolysis.
