Check Digit Verification of cas no
The CAS Registry Mumber 188-89-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,8 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 188-89:
(5*1)+(4*8)+(3*8)+(2*8)+(1*9)=86
86 % 10 = 6
So 188-89-6 is a valid CAS Registry Number.
