1246941-46-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1246941-46-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,9,4 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1246941-46:
(9*1)+(8*2)+(7*4)+(6*6)+(5*9)+(4*4)+(3*1)+(2*4)+(1*6)=167
167 % 10 = 7
So 1246941-46-7 is a valid CAS Registry Number.
