Check Digit Verification of cas no
The CAS Registry Mumber 72651-95-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,5 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72651-95:
(7*7)+(6*2)+(5*6)+(4*5)+(3*1)+(2*9)+(1*5)=137
137 % 10 = 7
So 72651-95-7 is a valid CAS Registry Number.
