Check Digit Verification of cas no
The CAS Registry Mumber 133886-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,8 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133886-89:
(8*1)+(7*3)+(6*3)+(5*8)+(4*8)+(3*6)+(2*8)+(1*9)=162
162 % 10 = 2
So 133886-89-2 is a valid CAS Registry Number.
