Check Digit Verification of cas no
The CAS Registry Mumber 2835-61-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,3 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2835-61:
(6*2)+(5*8)+(4*3)+(3*5)+(2*6)+(1*1)=92
92 % 10 = 2
So 2835-61-2 is a valid CAS Registry Number.
