Check Digit Verification of cas no
The CAS Registry Mumber 94928-86-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,9,2 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 94928-86:
(7*9)+(6*4)+(5*9)+(4*2)+(3*8)+(2*8)+(1*6)=186
186 % 10 = 6
So 94928-86-6 is a valid CAS Registry Number.
