1276577-56-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1276577-56-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,6,5,7 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1276577-56:
(9*1)+(8*2)+(7*7)+(6*6)+(5*5)+(4*7)+(3*7)+(2*5)+(1*6)=200
200 % 10 = 0
So 1276577-56-0 is a valid CAS Registry Number.
