156767-52-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 156767-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,7,6 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 156767-52:
(8*1)+(7*5)+(6*6)+(5*7)+(4*6)+(3*7)+(2*5)+(1*2)=171
171 % 10 = 1
So 156767-52-1 is a valid CAS Registry Number.
