142131-74-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142131-74-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,3 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142131-74:
(8*1)+(7*4)+(6*2)+(5*1)+(4*3)+(3*1)+(2*7)+(1*4)=86
86 % 10 = 6
So 142131-74-6 is a valid CAS Registry Number.
