812639-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 812639-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,2,6,3 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 812639-19:
(8*8)+(7*1)+(6*2)+(5*6)+(4*3)+(3*9)+(2*1)+(1*9)=163
163 % 10 = 3
So 812639-19-3 is a valid CAS Registry Number.
