1262299-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1262299-76-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,2,9 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1262299-76:
(9*1)+(8*2)+(7*6)+(6*2)+(5*2)+(4*9)+(3*9)+(2*7)+(1*6)=172
172 % 10 = 2
So 1262299-76-2 is a valid CAS Registry Number.
