1227678-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1227678-20-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,6,7 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1227678-20:
(9*1)+(8*2)+(7*2)+(6*7)+(5*6)+(4*7)+(3*8)+(2*2)+(1*0)=167
167 % 10 = 7
So 1227678-20-7 is a valid CAS Registry Number.
