129687-44-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 129687-44-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,6,8 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129687-44:
(8*1)+(7*2)+(6*9)+(5*6)+(4*8)+(3*7)+(2*4)+(1*4)=171
171 % 10 = 1
So 129687-44-1 is a valid CAS Registry Number.
