Check Digit Verification of cas no
The CAS Registry Mumber 121550-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,5 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 121550-98:
(8*1)+(7*2)+(6*1)+(5*5)+(4*5)+(3*0)+(2*9)+(1*8)=99
99 % 10 = 9
So 121550-98-9 is a valid CAS Registry Number.
