Check Digit Verification of cas no

The CAS Registry Mumber 1237789-42-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,7,7,8 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1237789-42:
(9*1)+(8*2)+(7*3)+(6*7)+(5*7)+(4*8)+(3*9)+(2*4)+(1*2)=192
192 % 10 = 2
So 1237789-42-2 is a valid CAS Registry Number.

Ethynyl MIDA boronate: A readily accessible and highly versatile building block for small molecule synthesis

Struble, Justin R.,Lee, Suk Joong,Burke, Martin D.

experimental part, p. 4710 - 4718 (2010/08/06)

Ethynyl N-methyliminodiacetic acid (MIDA) boronate is a very useful building block for small molecule synthesis. This compound can serve as both a bifunctional acetylene equivalent with the capacity for terminus-selective bis-functionalization and a versatile starting material for the preparation of a wide range of other MIDA boronate building blocks.
