812646-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 812646-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,2,6,4 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 812646-72:
(8*8)+(7*1)+(6*2)+(5*6)+(4*4)+(3*6)+(2*7)+(1*2)=163
163 % 10 = 3
So 812646-72-3 is a valid CAS Registry Number.
