Check Digit Verification of cas no
The CAS Registry Mumber 31775-97-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,7 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31775-97:
(7*3)+(6*1)+(5*7)+(4*7)+(3*5)+(2*9)+(1*7)=130
130 % 10 = 0
So 31775-97-0 is a valid CAS Registry Number.
