Check Digit Verification of cas no
The CAS Registry Mumber 173691-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,6,9 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 173691-08:
(8*1)+(7*7)+(6*3)+(5*6)+(4*9)+(3*1)+(2*0)+(1*8)=152
152 % 10 = 2
So 173691-08-2 is a valid CAS Registry Number.
