Check Digit Verification of cas no
The CAS Registry Mumber 71642-58-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,4 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71642-58:
(7*7)+(6*1)+(5*6)+(4*4)+(3*2)+(2*5)+(1*8)=125
125 % 10 = 5
So 71642-58-5 is a valid CAS Registry Number.
