127718-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127718-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,1 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127718-21:
(8*1)+(7*2)+(6*7)+(5*7)+(4*1)+(3*8)+(2*2)+(1*1)=132
132 % 10 = 2
So 127718-21-2 is a valid CAS Registry Number.
