102734-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102734-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,7,3 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 102734-97:
(8*1)+(7*0)+(6*2)+(5*7)+(4*3)+(3*4)+(2*9)+(1*7)=104
104 % 10 = 4
So 102734-97-4 is a valid CAS Registry Number.
