102918-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102918-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,9,1 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 102918-98:
(8*1)+(7*0)+(6*2)+(5*9)+(4*1)+(3*8)+(2*9)+(1*8)=119
119 % 10 = 9
So 102918-98-9 is a valid CAS Registry Number.
