Check Digit Verification of cas no
The CAS Registry Mumber 70321-85-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,3,2 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70321-85:
(7*7)+(6*0)+(5*3)+(4*2)+(3*1)+(2*8)+(1*5)=96
96 % 10 = 6
So 70321-85-6 is a valid CAS Registry Number.
