142822-39-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142822-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,2 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 142822-39:
(8*1)+(7*4)+(6*2)+(5*8)+(4*2)+(3*2)+(2*3)+(1*9)=117
117 % 10 = 7
So 142822-39-7 is a valid CAS Registry Number.
