718646-39-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 718646-39-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,8,6,4 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 718646-39:
(8*7)+(7*1)+(6*8)+(5*6)+(4*4)+(3*6)+(2*3)+(1*9)=190
190 % 10 = 0
So 718646-39-0 is a valid CAS Registry Number.
