Check Digit Verification of cas no
The CAS Registry Mumber 91912-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,1 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91912-97:
(7*9)+(6*1)+(5*9)+(4*1)+(3*2)+(2*9)+(1*7)=149
149 % 10 = 9
So 91912-97-9 is a valid CAS Registry Number.
