1227680-59-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1227680-59-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,6,8 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1227680-59:
(9*1)+(8*2)+(7*2)+(6*7)+(5*6)+(4*8)+(3*0)+(2*5)+(1*9)=162
162 % 10 = 2
So 1227680-59-2 is a valid CAS Registry Number.
