Check Digit Verification of cas no
The CAS Registry Mumber 501902-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,9,0 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 501902-06:
(8*5)+(7*0)+(6*1)+(5*9)+(4*0)+(3*2)+(2*0)+(1*6)=103
103 % 10 = 3
