1246962-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1246962-63-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,9,6 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1246962-63:
(9*1)+(8*2)+(7*4)+(6*6)+(5*9)+(4*6)+(3*2)+(2*6)+(1*3)=179
179 % 10 = 9
So 1246962-63-9 is a valid CAS Registry Number.
