342643-82-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 342643-82-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,6,4 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 342643-82:
(8*3)+(7*4)+(6*2)+(5*6)+(4*4)+(3*3)+(2*8)+(1*2)=137
137 % 10 = 7
So 342643-82-7 is a valid CAS Registry Number.
