127921-51-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127921-51-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,2 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127921-51:
(8*1)+(7*2)+(6*7)+(5*9)+(4*2)+(3*1)+(2*5)+(1*1)=131
131 % 10 = 1
So 127921-51-1 is a valid CAS Registry Number.
