Check Digit Verification of cas no
The CAS Registry Mumber 1201667-47-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,6,6 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1201667-47:
(9*1)+(8*2)+(7*0)+(6*1)+(5*6)+(4*6)+(3*7)+(2*4)+(1*7)=121
121 % 10 = 1
So 1201667-47-1 is a valid CAS Registry Number.
