Check Digit Verification of cas no
The CAS Registry Mumber 73872-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,7 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73872-31:
(7*7)+(6*3)+(5*8)+(4*7)+(3*2)+(2*3)+(1*1)=148
148 % 10 = 8
So 73872-31-8 is a valid CAS Registry Number.
