Check Digit Verification of cas no
The CAS Registry Mumber 77332-90-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,3 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77332-90:
(7*7)+(6*7)+(5*3)+(4*3)+(3*2)+(2*9)+(1*0)=142
142 % 10 = 2
So 77332-90-2 is a valid CAS Registry Number.
