127766-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127766-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,6 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127766-72:
(8*1)+(7*2)+(6*7)+(5*7)+(4*6)+(3*6)+(2*7)+(1*2)=157
157 % 10 = 7
So 127766-72-7 is a valid CAS Registry Number.
