Check Digit Verification of cas no
The CAS Registry Mumber 133378-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,7 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133378-08:
(8*1)+(7*3)+(6*3)+(5*3)+(4*7)+(3*8)+(2*0)+(1*8)=122
122 % 10 = 2
So 133378-08-2 is a valid CAS Registry Number.
