145222-70-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145222-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,2 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 145222-70:
(8*1)+(7*4)+(6*5)+(5*2)+(4*2)+(3*2)+(2*7)+(1*0)=104
104 % 10 = 4
So 145222-70-4 is a valid CAS Registry Number.

Asymmetric Ring Transformation of meso-7-Substituted Bicyclooctanones into Chiral Bicyclooctene Derivatives
Yamamoto, Takayoshi,Suemune, Hiroshi,Sakai, Kiyoshi
, p. 1482 - 1483 (2007/10/02)
Asymmetric ring transformation of meso-7-(2-oxoalkyl)bicyclooctan-3-ones into chiral bicyclooct-2-ene derivatives is accomplished by treatment with chiral cyclic (six- or seven-mebered ring) 1,2-diols-BF3-Et2O.
