Check Digit Verification of cas no
The CAS Registry Mumber 92208-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,2,0 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 92208-13:
(7*9)+(6*2)+(5*2)+(4*0)+(3*8)+(2*1)+(1*3)=114
114 % 10 = 4
So 92208-13-4 is a valid CAS Registry Number.
