Check Digit Verification of cas no
The CAS Registry Mumber 437651-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,7,6,5 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 437651-47:
(8*4)+(7*3)+(6*7)+(5*6)+(4*5)+(3*1)+(2*4)+(1*7)=163
163 % 10 = 3
