1276129-49-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1276129-49-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,6,1,2 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1276129-49:
(9*1)+(8*2)+(7*7)+(6*6)+(5*1)+(4*2)+(3*9)+(2*4)+(1*9)=167
167 % 10 = 7
So 1276129-49-7 is a valid CAS Registry Number.
