Check Digit Verification of cas no

The CAS Registry Mumber 895570-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,5,5,7 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 895570-54:
(8*8)+(7*9)+(6*5)+(5*5)+(4*7)+(3*0)+(2*5)+(1*4)=224
224 % 10 = 4
So 895570-54-4 is a valid CAS Registry Number.

Efficient C-C double-bond formation reaction via a new synthetic strategy: A self-sorting tandem reaction

Yin, Guodong,Zhou, Baohan,Meng, Xianggao,Wu, Anxin,Pan, Yuanjiang

, p. 2245 - 2248 (2006)

A novel and efficient carbon-carbon double-bond formation reaction via coupling of aryl or heteroaryl methyl ketones has been developed. A dimethyl sulfoxide-iodine-CuO system was proven to be efficient for this reaction and afforded the expected products in good yields. A new synthetic strategy, a self-sorting tandem reaction, was involved in this type of reaction and was presented for the first time.
