Check Digit Verification of cas no
The CAS Registry Mumber 21936-10-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,3 and 6 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21936-10:
(7*2)+(6*1)+(5*9)+(4*3)+(3*6)+(2*1)+(1*0)=97
97 % 10 = 7
So 21936-10-7 is a valid CAS Registry Number.
