1146577-77-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1146577-77-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,6,5,7 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1146577-77:
(9*1)+(8*1)+(7*4)+(6*6)+(5*5)+(4*7)+(3*7)+(2*7)+(1*7)=176
176 % 10 = 6
So 1146577-77-6 is a valid CAS Registry Number.
