1256451-31-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1256451-31-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,4,5 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1256451-31:
(9*1)+(8*2)+(7*5)+(6*6)+(5*4)+(4*5)+(3*1)+(2*3)+(1*1)=146
146 % 10 = 6
So 1256451-31-6 is a valid CAS Registry Number.
