The CAS Registry Mumber 157629-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,6,2 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.Calculate Digit Verification of CAS Registry Number 157629-95:
(8*1)+(7*5)+(6*7)+(5*6)+(4*2)+(3*9)+(2*9)+(1*5)=173
173 % 10 = 3
So 157629-95-3 is a valid CAS Registry Number.
