Check Digit Verification of cas no
The CAS Registry Mumber 1333332-94-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,3,3 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1333332-94:
(9*1)+(8*3)+(7*3)+(6*3)+(5*3)+(4*3)+(3*2)+(2*9)+(1*4)=127
127 % 10 = 7
So 1333332-94-7 is a valid CAS Registry Number.
