342900-66-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 342900-66-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,9,0 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 342900-66:
(8*3)+(7*4)+(6*2)+(5*9)+(4*0)+(3*0)+(2*6)+(1*6)=127
127 % 10 = 7
So 342900-66-7 is a valid CAS Registry Number.
