642478-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 642478-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,4,7 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 642478-44:
(8*6)+(7*4)+(6*2)+(5*4)+(4*7)+(3*8)+(2*4)+(1*4)=172
172 % 10 = 2
