1267623-13-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1267623-13-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,7,6,2 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1267623-13:
(9*1)+(8*2)+(7*6)+(6*7)+(5*6)+(4*2)+(3*3)+(2*1)+(1*3)=161
161 % 10 = 1
So 1267623-13-1 is a valid CAS Registry Number.
