129237-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129237-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,3 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129237-21:
(8*1)+(7*2)+(6*9)+(5*2)+(4*3)+(3*7)+(2*2)+(1*1)=124
124 % 10 = 4
So 129237-21-4 is a valid CAS Registry Number.
