Check Digit Verification of cas no
The CAS Registry Mumber 71872-77-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,7 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 71872-77:
(7*7)+(6*1)+(5*8)+(4*7)+(3*2)+(2*7)+(1*7)=150
150 % 10 = 0
So 71872-77-0 is a valid CAS Registry Number.
