Check Digit Verification of cas no
The CAS Registry Mumber 3946-10-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,4 and 6 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3946-10:
(6*3)+(5*9)+(4*4)+(3*6)+(2*1)+(1*0)=99
99 % 10 = 9
So 3946-10-9 is a valid CAS Registry Number.
