Check Digit Verification of cas no
The CAS Registry Mumber 90477-04-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,7 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90477-04:
(7*9)+(6*0)+(5*4)+(4*7)+(3*7)+(2*0)+(1*4)=136
136 % 10 = 6
