Check Digit Verification of cas no
The CAS Registry Mumber 501697-55-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,6,9 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 501697-55:
(8*5)+(7*0)+(6*1)+(5*6)+(4*9)+(3*7)+(2*5)+(1*5)=148
148 % 10 = 8
So 501697-55-8 is a valid CAS Registry Number.
