1217660-47-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1217660-47-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,6,6 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1217660-47:
(9*1)+(8*2)+(7*1)+(6*7)+(5*6)+(4*6)+(3*0)+(2*4)+(1*7)=143
143 % 10 = 3
So 1217660-47-3 is a valid CAS Registry Number.
