1281979-77-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1281979-77-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,1,9,7 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1281979-77:
(9*1)+(8*2)+(7*8)+(6*1)+(5*9)+(4*7)+(3*9)+(2*7)+(1*7)=208
208 % 10 = 8
So 1281979-77-8 is a valid CAS Registry Number.
