Check Digit Verification of cas no
The CAS Registry Mumber 2870-32-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,7 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2870-32:
(6*2)+(5*8)+(4*7)+(3*0)+(2*3)+(1*2)=88
88 % 10 = 8
So 2870-32-8 is a valid CAS Registry Number.
