1256451-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1256451-21-4 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, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1256451-21:
(9*1)+(8*2)+(7*5)+(6*6)+(5*4)+(4*5)+(3*1)+(2*2)+(1*1)=144
144 % 10 = 4
So 1256451-21-4 is a valid CAS Registry Number.
