5Check Digit Verification of cas no
The CAS Registry Mumber 71902-15-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,0 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.Calculate Digit Verification of CAS Registry Number 71902-15:
(7*7)+(6*1)+(5*9)+(4*0)+(3*2)+(2*1)+(1*5)=113
113 % 10 = 3
So 71902-15-3 is a valid CAS Registry Number.
