Check Digit Verification of cas no

The CAS Registry Mumber 1304772-10-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,7,7 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1304772-10:
(9*1)+(8*3)+(7*0)+(6*4)+(5*7)+(4*7)+(3*2)+(2*1)+(1*0)=128
128 % 10 = 8
So 1304772-10-8 is a valid CAS Registry Number.

Sapkota, Kiran,Roh, Eunmiri,Lee, Eunyoung,Ha, Eun-Mi,Yang, Jae-Ho,Lee, Eung-Seok,Kwon, Youngjoo,Kim, Youngsoo,Na, Younghwa

experimental part, p. 2168 - 2175 (2011/05/11)

In order to develop potent skin whitening agents, we have synthesized 17 hydroxyphenyl benzyl ether compounds and tested their melanin synthesis inhibitory activity, DPPH free radical scavenging activity and tyrosinase inhibitory activity. Compounds 32, 35 and 36 possessing 4-hydroxyphenyl benzyl ether structure showed excellent inhibitory capacity with almost 50-fold than arbutin used as a reference in the inhibition test of α-MSH stimulated melanin synthesis in B-16 cells. 4-Hydroxyphenyl benzyl ether compounds also showed good antioxidant activity in the DPPH free radical scavenging test. The tyrosinase function was effectively inhibited by 3,5-dihydroxyphenyl benzyl ether analogues, especially compounds 18, 22, and 24.
