Check Digit Verification of cas no
The CAS Registry Mumber 131941-33-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,4 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131941-33:
(8*1)+(7*3)+(6*1)+(5*9)+(4*4)+(3*1)+(2*3)+(1*3)=108
108 % 10 = 8
So 131941-33-8 is a valid CAS Registry Number.
