Check Digit Verification of cas no
The CAS Registry Mumber 51621-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,2 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51621-57:
(7*5)+(6*1)+(5*6)+(4*2)+(3*1)+(2*5)+(1*7)=99
99 % 10 = 9
So 51621-57-9 is a valid CAS Registry Number.
