189310-92-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189310-92-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,1 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 189310-92:
(8*1)+(7*8)+(6*9)+(5*3)+(4*1)+(3*0)+(2*9)+(1*2)=157
157 % 10 = 7
So 189310-92-7 is a valid CAS Registry Number.
