74213-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74213-87-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,1 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74213-87:
(7*7)+(6*4)+(5*2)+(4*1)+(3*3)+(2*8)+(1*7)=119
119 % 10 = 9
So 74213-87-9 is a valid CAS Registry Number.
