Check Digit Verification of cas no
The CAS Registry Mumber 21997-30-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,9 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21997-30:
(7*2)+(6*1)+(5*9)+(4*9)+(3*7)+(2*3)+(1*0)=128
128 % 10 = 8
So 21997-30-8 is a valid CAS Registry Number.
