Check Digit Verification of cas no
The CAS Registry Mumber 1621066-74-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,0,6 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1621066-74:
(9*1)+(8*6)+(7*2)+(6*1)+(5*0)+(4*6)+(3*6)+(2*7)+(1*4)=137
137 % 10 = 7
So 1621066-74-7 is a valid CAS Registry Number.
