Check Digit Verification of cas no
The CAS Registry Mumber 166524-65-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,5,2 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 166524-65:
(8*1)+(7*6)+(6*6)+(5*5)+(4*2)+(3*4)+(2*6)+(1*5)=148
148 % 10 = 8
So 166524-65-8 is a valid CAS Registry Number.
