Check Digit Verification of cas no
The CAS Registry Mumber 98476-09-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,7 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98476-09:
(7*9)+(6*8)+(5*4)+(4*7)+(3*6)+(2*0)+(1*9)=186
186 % 10 = 6
So 98476-09-6 is a valid CAS Registry Number.
