1262749-10-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1262749-10-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,7,4 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1262749-10:
(9*1)+(8*2)+(7*6)+(6*2)+(5*7)+(4*4)+(3*9)+(2*1)+(1*0)=159
159 % 10 = 9
So 1262749-10-9 is a valid CAS Registry Number.
