142437-92-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142437-92-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,3 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 142437-92:
(8*1)+(7*4)+(6*2)+(5*4)+(4*3)+(3*7)+(2*9)+(1*2)=121
121 % 10 = 1
So 142437-92-1 is a valid CAS Registry Number.
