167971-41-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 167971-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,9,7 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 167971-41:
(8*1)+(7*6)+(6*7)+(5*9)+(4*7)+(3*1)+(2*4)+(1*1)=177
177 % 10 = 7
So 167971-41-7 is a valid CAS Registry Number.
