1177417-12-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1177417-12-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,7,4,1 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1177417-12:
(9*1)+(8*1)+(7*7)+(6*7)+(5*4)+(4*1)+(3*7)+(2*1)+(1*2)=157
157 % 10 = 7
So 1177417-12-7 is a valid CAS Registry Number.
