1221237-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1221237-89-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,2,3 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1221237-89:
(9*1)+(8*2)+(7*2)+(6*1)+(5*2)+(4*3)+(3*7)+(2*8)+(1*9)=113
113 % 10 = 3
So 1221237-89-3 is a valid CAS Registry Number.
