1217887-61-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1217887-61-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,8,8 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1217887-61:
(9*1)+(8*2)+(7*1)+(6*7)+(5*8)+(4*8)+(3*7)+(2*6)+(1*1)=180
180 % 10 = 0
So 1217887-61-0 is a valid CAS Registry Number.
