142644-74-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142644-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,4 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142644-74:
(8*1)+(7*4)+(6*2)+(5*6)+(4*4)+(3*4)+(2*7)+(1*4)=124
124 % 10 = 4
So 142644-74-4 is a valid CAS Registry Number.
