Check Digit Verification of cas no
The CAS Registry Mumber 129286-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,8 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129286-37:
(8*1)+(7*2)+(6*9)+(5*2)+(4*8)+(3*6)+(2*3)+(1*7)=149
149 % 10 = 9
So 129286-37-9 is a valid CAS Registry Number.
