1290633-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1290633-55-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,6,3 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1290633-55:
(9*1)+(8*2)+(7*9)+(6*0)+(5*6)+(4*3)+(3*3)+(2*5)+(1*5)=154
154 % 10 = 4
So 1290633-55-4 is a valid CAS Registry Number.
