Check Digit Verification of cas no
The CAS Registry Mumber 53891-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,8,9 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 53891-22:
(7*5)+(6*3)+(5*8)+(4*9)+(3*1)+(2*2)+(1*2)=138
138 % 10 = 8
So 53891-22-8 is a valid CAS Registry Number.
