194342-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 194342-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,3,4 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 194342-89:
(8*1)+(7*9)+(6*4)+(5*3)+(4*4)+(3*2)+(2*8)+(1*9)=157
157 % 10 = 7
So 194342-89-7 is a valid CAS Registry Number.
