3246-21-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3246-21-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,4 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3246-21:
(6*3)+(5*2)+(4*4)+(3*6)+(2*2)+(1*1)=67
67 % 10 = 7
So 3246-21-7 is a valid CAS Registry Number.
