Check Digit Verification of cas no
The CAS Registry Mumber 389082-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,9,0,8 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 389082-83:
(8*3)+(7*8)+(6*9)+(5*0)+(4*8)+(3*2)+(2*8)+(1*3)=191
191 % 10 = 1
So 389082-83-1 is a valid CAS Registry Number.
