61670-15-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61670-15-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,6,7 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 61670-15:
(7*6)+(6*1)+(5*6)+(4*7)+(3*0)+(2*1)+(1*5)=113
113 % 10 = 3
So 61670-15-3 is a valid CAS Registry Number.
