Check Digit Verification of cas no
The CAS Registry Mumber 201854-70-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,8,5 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 201854-70:
(8*2)+(7*0)+(6*1)+(5*8)+(4*5)+(3*4)+(2*7)+(1*0)=108
108 % 10 = 8
So 201854-70-8 is a valid CAS Registry Number.
