102342-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102342-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,3,4 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 102342-57:
(8*1)+(7*0)+(6*2)+(5*3)+(4*4)+(3*2)+(2*5)+(1*7)=74
74 % 10 = 4
So 102342-57-4 is a valid CAS Registry Number.
