Check Digit Verification of cas no
The CAS Registry Mumber 890643-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,6,4 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 890643-73:
(8*8)+(7*9)+(6*0)+(5*6)+(4*4)+(3*3)+(2*7)+(1*3)=199
199 % 10 = 9
So 890643-73-9 is a valid CAS Registry Number.
